Correct wording of polling interval in UPS docs

Hey,

The docs (12.17 in the green tip box) for UPS configuration state "If this error occurs, increase the polling frequency by adding an entry to Auxiliary Parameters (ups.conf): pollinterval = 10. The default polling frequency is two seconds."

However, by setting pollinterval to 10 you are not increasing the frequency of polling, rather you are decreasing it. So that "increase" should be changed to "decrease".
